Direct Port System Plumbing

The Nitrous Outlet Direct Port System provides adjustable horse power levels from 200 to 2000 HP and is designed to install into just about any intake manifold. The unique design of the Direct Port System provides the most precise cylinder to cylinder distribution possible. The Nitrous and Fuel enter through the front and rear passage of the rail, filling the inner channel, feeding each hardline, flowing to each nozzle and discharging directly into each intake runner. The nitrous and fuel jets are located at each nozzle, providing the capability to adjust the amount of nitrous and fuel volume into each individual cylinder.

Not only does the Direct Port system provide a really clean installation but is a perfect option for the racer using a large amount of nitrous and needing the capability of individual cylinder tuning.

How does the Direct Port System compare to an Inner Plenum Direct Port System or Plate System?

• Direct Port:

The Direct Port System is similar to an Inner Plenum direct-port application in the sense that it is discharging directly into each individual intake runner, allowing the ability to adjust nitrous and fuel volume per intake runner, however it is mounted on the outside of the intake manifold which makes jet changes easier.

• Nitrous Plates:

The Direct Port System uses a completely different technology than the Nitrous Plates,  which are designed to bolt between the throttle body / Carburetor and intake manifold. Nitrous Plates are designed to saturate the intake plenums incoming air flow, allowing the engine to pull the atomized mixture into each intake runner and do not have the ability to adjust nitrous and fuel volume per intake runner.

Construction:

The Nitrous Outlet Direct Port System is custom built to each intake manifolds unique requirements. The Direct Port is designed to work with just about any intake manifold The installation of the Direct Port System requires sending the intake manifold to Nitrous Outlet. Nitrous Outlet machines the intake and components, then installs them making sure that the discharge ports perfectly align into each intake runner.

Optional Upgrades:

• Stacked Systems: Whether the application requires one system or 6 systems we got you covered
• Nozzle Bungs: Bungs are needed on most intakes in order to use Annular nozzles.
• Purge Hardline: Hard lining a purge solenoid between the nitrous solenoids provides a way to evacuate air out of the feed, all the way up through the base of the solenoids, ridding the system of any delays or surges resulting in an improves 60 ft. and ET at the track.
• Fuel Hardline: Popular on most EFI applications, hard lining the fuel feed provides a nice clean installation.
• Hardline Powder Coating: Powder coating the hardline is a great way to add sex appeal and color to your intake manifold.
• Intake Powder Coating: Sand Blasting and Powder Coating the intake manifold is not only a great way to add sex appeal and color to the intake. but provides an easy to clean surface and a way to bring an old intake back to life.
